What is the spacing of the riser supports of the fire pipe network?

The distance between the risers of the fire pipe network with a diameter of 100 meters. The diameter of the fire pipe network riser is three meters. It is five meters that are not insulated.

In fact, the bracket is a construction experience work, the pipe network riser is connected in different ways, different installation positions, then the style of the bracket will be different, the installation spacing is also different, I will give you a general introduction.

1. The style of the bracket: The main styles of the bracket are:"doors"Type or "U" bracket, also called anti-sway bracket (mostly used in DN100 and above pipe diameter), "L" type or "angle" bracket (mostly used in small pipe diameter and wall riser).

2. The spacing of the bracket: the maximum spacing of the bracket is standardized, which you can, but the spacing of the bracket is smaller than the specification during the actual installation, and the flange is connected.

The spacing of the brackets in the case of threaded connection is higher than that of the grooved connection.

When it is big. Take the most common trench in fire protection as an example: the bracket spacing of DN65 DN150 is generally about 4 meters (the bracket spacing is related to the span of the beam, because the bracket is often installed on the beam side), and the bracket spacing of DN25 DN50 is generally about 3 meters.

3. Material selection of the bracket: 5 angle steel will be selected for the pipe network riser of single DN100 and single DN150.

or 5 channels or 6 channels; When two brackets are shared, 8 or 10 channels of steel will be selected; When the three pipes are shared, 10 or 12 channels of steel will be selected; DN50 DN80 is used in smaller amounts in spray and DN65 is used in fire hydrants.

The amount is more, and it is generally considered according to 5 angle steel; DN25 DN40 is generally considered as 3 or 4 angle steel.

4. Bracket calculation: The length of the boom is indeed the key when calculating the bracket, so it is necessary to determine the elevation of the pipe network riser and the elevation of the bottom of the floor slab (because the fire pipe is generally installed at the bottom of the beam, so the beam height is very critical), and the general basement bracket boom is longer, and the floor is slightly shorter.

Therefore, the sprinkler pipe bracket is roughly estimated: 150 100 pipes according to 5 channel steel spacing meters, "U" type support, a single bracket with material meters, 80 65 50 pipes according to 5 angle steel spacing meters, "U" type bracket, a single bracket with material meters, 40 32 25 pipes according to 4 angle steel spacing meters, "L" type bracket, a single bracket with timber meters.

Generally, refer to the practice of indoor water supply pipe support.

The spacing between pipe supports or hangers should not be greater than the requirements of the following table:

When the pipeline through the beam is installed, the beam through the beam should be used as a hanger;

The following parts should be provided with a fixed bracket or an anti-swaying bracket:

1) The water distribution pipe should be provided with an anti-swaying bracket at the midpoint, but it can not be set when the pipe diameter is less than DN50;

2) The length of the water distribution main pipe and water distribution pipe, the length of the water distribution branch pipe is more than 15m, and at least 1 anti-swaying bracket should be set up in every 15m length, but when the pipe diameter is not greater than DN40, it can not be set;

3) One anti-swaying bracket should be set at the bending, tee and tee positions of the pipeline with a pipe diameter greater than DN50.

There should be no less than 1 anti-sway bracket for each section of the overhead pipeline; When the pipeline changes direction, an anti-sway bracket should be added; The riser should be fixed with anti-swaying brackets at its beginning and end or with pipe clamps.

Hello dear! Fire pipe support spacing installation: the hanger set on each pipe section on the water distribution pipe and the pipe section between the adjacent two sprinklers should not be less than one, when the distance between the sprinkler heads is less than 1.8 meters, the hanger can be set up at intervals, but the spacing of the hanger should not be greater than 3.6 meters.

The vertically installed water distribution main pipe should be fixed with anti-swaying brackets or pipe clamps at its beginning and end, and the distance between its installation position and the ground or floor should be 1.5 to 1.8 meters.

meters of fire pipes with a bracket.

Fire pipe is used for fire fighting, connecting fire fighting equipment, equipment, transporting fire extinguishing water, gas or other media pipeline materials, due to special needs, the thickness and material of fire pipe have special requirements, and spray red paint, transport fire water.

There are more than or equal to DN65 or more domestic water supply and fire pipe system requires 12 meters to install a lateral seismic support.

24 meters to install a longitudinal seismic bracket. All duct systems with diameters greater than or equal require a lateral seismic support of 9 meters.

18 meters to install a longitudinal seismic bracket for the power system.

Pipes and cable trays.

All electrical piping with an inner diameter greater than or equal to 60mm and all cable trays with a gravity greater than or equal to 150n m in the system.

Pipe classification: alloy pipe:

Alloy pipes are seamless steel pipes.

Its performance is much higher than that of the general seamless steel pipe, because this kind of steel pipe contains more CR, and its high temperature resistance, low temperature resistance, and spine rubber corrosion resistance are not comparable to other seamless steel pipes, so alloy pipes are widely used in the oil, aerospace, chemical, electric power, boiler, military and other industries.

Composite pipes:

Composite pipe is a pipe made of two or more materials, which is based on metal pipes, and is welded with polyethylene and cross-linked polyethylene inside and outside.

and other non-metallic materials forming, with the advantages of metal pipes and non-metallic pipes.

Plastic pipes: As an important part of chemical building materials, plastic pipes are widely accepted by users for their superior performance, hygiene, environmental protection, low consumption, etc., mainly including UPVC drainage pipes, UPVC water supply pipes, aluminum-plastic composite pipes, and polyethylene (PE) water supply pipes.

The spacing of fire pipe supports or hangers should not be greater than the requirements of the following table;

When the pipeline through the beam is installed, the beam through the beam should be used as a hanger;

6. The following parts should be provided with fixed brackets or anti-swaying brackets:

1) The water distribution pipe should be provided with an anti-swaying bracket at the midpoint, but it can not be set when the pipe diameter is less than DN50;

2) The length of the water distribution main pipe and water distribution pipe, the length of the water distribution branch pipe is more than 15m, and at least 1 anti-swaying bracket should be set up in every 15m length, but when the pipe diameter is not greater than DN40, it can not be set;

3) One anti-swaying bracket should be set at the bending, tee and tee positions of the pipeline with a pipe diameter greater than DN50.

4) The strength of the anti-swaying bracket should meet the weight of the pipe, fittings and water in the pipe and add 50% of the horizontal thrust without damage or permanent deformation; When the pipe through the beam is installed, the pipe is fixed to the concrete structure with fasteners, which should be treated as one anti-sway support.

Fire pipe is used for fire fighting, connecting fire fighting equipment and equipment, and transporting fire fighting water, gas or other media pipeline materials; Due to special needs, the thickness and material of the fire pipe have special requirements, and red paint is sprayed to transport fire water.

Fire pipe support calculation Example: How many meters is a bracket for a DN150 pipe?

Hello, the galvanized steel pipe bracket of DN150 is generally an anti-swaying bracket, similar to a U-shaped bracket, and a single length is calculated according to this; 1 side length * 2 + cross arm 2 The length of the cross arm can be calculated according to the book Lu Chun 100 + 100 + 150 = 350 3 side length I generally count it as 1 meter meter To sum up: DN150 galvanized steel pipe a bracket, for the No. 5 angle steel meter 3 meters.
